for debugging purposes, how do I see the ModelState errors from code in the action method? ModelState.IsValid returns false. I want to copy the error messages to a variable so I can display them in the debugger.

My problem is that though there are values in the modelstate, the error messages are not being displayed in the View. What is wrong with my code?

I want to perform some simple form validation in my controller.
Here's an excerpt from the controller action:
[code]....
It appears that must use a string as the error's key. Is there a way i can generate the corect key from the model, or should I just check for what input name Html.PasswordFor(x => x.NewPassword) returns?
Im using the following code:
[code]....
To return a partial view and a form through JSON. It works as it should, but as soon as I get modelstate errors my ValidationSummary does not show. The JSON only return the default form but it does not highlight the validation errors or show the validation summary.
Am I missing something?
This is how I call the RenderPartialToString:
string partialView = RenderPartialToString(this.ControllerContext, "~/Areas/User/Views/Account/ChangeAccountDetails.ascx", new ViewDataDictionary(avd), new TempDataDictionary());
Imagine, a model like this:
[AddressValidation]
public AddressType[] Address { get; set; }
internal class AddressValidation : ValidationAttribute
{
public override bool IsValid(object value)
{
//Assume we are valid
var isValid = true;
//Cast to something useful
var addresses = (AddressType[])value;
var defaultAddresses = addresses.Count(a => a.AddressCode == AddressCodeEnum.@default);
if (defaultAddresses == 0)
{
ErrorMessage = "One address must be the default address";
isValid = false;
}
else if (defaultAddresses > 1)
{
ErrorMessage = "Only one address can be the default address";
isValid = false;
}
//Return the result
return isValid;
}
}
When the model is validated by the controller, any of the subordinate addresses are properly validated and any errors are returned as modelstate errors. However, the custom attribute's error is never added to modelstate, even though it validates false. It seems as if this should work, the validation is called and I can step through it - it just never gets added to modelstate.
How to send the modelstate errors or any other exception to the view via ajax?
View 3 Repliesi just want to be able to call a javascritp subroutine on the client, after the server has done its thing (when an action completes or control goes to the view, i'd dont mind calling the js from the view either).
for some reason, even vs2010 doesn't let me put breakpoints in <% ... %> tagged areas between <script...> and </script> tagged areas. i for this reason can't figure out whats going on and how it's running things. here is what i've put in my view, and the javascritp should run, but it doesn't....
im just trying to call "RunOnceRoutines;" but it's not getting called!
the 2 questions: how on earth do we call javascript methods from server, and where is all this lovely javascript debugging i've heard about since vs2008? no where to be found!

In one view (view1) there is a text box and a button beside it. i click on that button, i am popping another view (Create view) as a seperate window. in create view i am entering some values and creating a record in db. out of these values one value i have to send back to "View1". how can i send this value? i am opening view2 from view1 like
<input type="button" value="Get ID"
onclick="window.open('<%=Url.Action("Create","Controller1") %>',
'','scrollbars=yes,width=800,height=800,resizable=yes');"
/>
View2 contains some fields like Name,Email etc... and I click "Create" to call HTTPPOST. there i add the values to db including a generated guid. i want to send this ID to view1.
When i try to insert values from textbox to db the values are not getting inside controllers action method.

I am using ASP.NET MVC 1. I want to pass an int value to from an action to view. I can use 2 ways.
Use ViewData dictionary.
Define a class to contain the int value.
Other these two, Is there a way to pass the int value to view so that I can get the int value using just Model like
<label><%= Model %></label>
Is it necessary to do a ModelState.IsValid check at the top of every action? It seems that it is since the default model binder could make it invalid depending on the action parameters.
View 3 RepliesI am having a dropdown server control on view, when the user clicks the submit btn at that time the form gets posted. and a action method in view controller is called with verb=post.
But the problem is that how should i get reference to the dropdown server control in the action method of view controller?
I have the Index action method calling a method that itself is an action method.
Example :

What to do in this case ?
I am desiging a master and details page from a search page..user can search for something and I need to display the result in jqgrid if the result has more than 1 row or record.. if the result is just one record then i have to directly send then to details page by skiping grid page... I do have an action method for results page and one more action method for Jqgrid data..i am trying to check the row count for the database result and trying to redirect to details action results..but its not working at all..and showing an empty jqgrid..

I've written a View (form) that has a section with two radio buttons and a blank <DIV> block that will dynamically be updated. When one radio button is clicked, a <DIV> on the page is updated with fields specific to that radio button option. When the other radio button is clicked, the <DIV> on the page is updated with fields specific to that radio button option. To determine what content gets displayed when a radio option is selected, I call a JavaScript function and set the content appropriately using jQuery. Pretty easy so far. Let's assume that the User has toggled the radio buttons and filled in some data. Further down in the form, the User has entered an invalid e-mail address. When the User submits the View, the ModelState is invalid. If it is invalid, I return the View.
[Code]....
Problem is, when the View is returned, some of the form fields (that are static) are in place. However, the <DIV> that was previously updated based on User radio button selections is reset to its original state. When we return a View because of an invalid Model State, is MVC smart enough to return the View in it's modified state (in this case, with the modified DIV and dynamically added content)?
I've been working with MVC 2 for awhile and ive done ReturnToAction as well as ValidationSummary - but this is a little different in that my "submit" buttons are controls by javascript/JQuery - i debug the action and it does go into the correct Controller Action but once it passes over RedirecToAction, nothing happens....
My second problem is that my ValidationSummary fails to show - i run a test and when it returns a View when ModelState is invalid - nothing shows up
Is it a problem with my buttons/forms/submit/JQuery?
[Code]....
And the Controller looks like this:
[Code]....
My Services handle things like validation, I pass it the ModelState and a ModelStateDictionary wrapper and add errors - am i adding errors incorrectly?

After wading through quite a few articles on creating modal forms (using partial views and jquery) I got things working fine for my login....as long as you enter a valid login though!
What I did:
Created a partial view containing my login form.
In my action controller, the get action just return a PartialViewResult, which get dealt with by a bit of jQuery in my master:[Code]....
Like I said this works fine. Now the post action of my login check if it's a valid login, and if so send the user to the passed returnurl or the home page.
However, if the validation fails, I now return the partial view again, which work , but the partial get displayed by itself instead of rendering in the modal form that was opened by jquery.
I'm being tasked with making changes to an asp.net application and really have no experience working with them other than dabbling in VWD.I was given a zip file of the directory containing the files. It was developed in VWD 2005. . My question is a general one: Are there steps I need to take (regenerate web.config file? change settings of some sort?) in order to get started? The application is functional on the web server.

I would like to create one view for my CRUD actions. The view contains 3 basic DIV updatetargets ("search form", "search result listing" and "action" (would be create,detail,edit,delete). Basic flow would be: "Search" updates the "Search Result Listing", click on CRUD actions in listing would show partial view in "action".
how do I call to refresh the "Listing" after I do any add/update/delete without having user click search again?

How can I make an AJAX call to retrieve the URL of controller's action method?
View 2 RepliesI've been using the new ASP.Net MVC 3 RemoteAttribute to send a remote call to an action method that had a single parameter. Now I want to pass in a second parameter using the AdditionalFields property:
[Remote("IsEmailAvailable", "Users", AdditionalFields = "InitialEmail")]
Where IntialEmail is a hidden field in the view. The action looks like so:
public JsonResult IsEmailAvailable(string email,string InitialEmail){//etc.}
When the view is rendered, the hidden field is populated, but when the Action method is triggered remotely, the value is an empty string.
I've seen elsewhere case sensitivity may be an issue, so I've ensured the Action method has the same case for both parameters.
I have 2 views for a input operation in my application.
The first view (lets call it view1) submits a form. Based on the form some operations on database is done and second view(View2) is returned with some other data from the database as a model.
[Code]....
Now, since I return a new view and not a action redirect the url is still http://url/View1 but everything works as it is supposed to.
When I submit the form in View2 it calls the View1 action method, not the View2 action method. Probably because the url is still View1.
public ActionResult RenderMyThing(IList<String> strings)
{
return View("RenderMyView");
}
How do I pass in strings?
routes.MapRoute("MyRoute", "RenderMyThing.aspx", new { controller = "My", action = "RenderMyThing" });
Is there a way I could pass in strings here?
Secondly, how does ASP.NET MVC know that action is my action, and controller is my controller. Like I saw this in samples, and it does work, but isn't it just an anonymous object with no type?
I'm trying to use the jQuery.post() function to post an object to an action method, but for some reason the nested objects aren't initialised properly when they're received by the action method.
Here's my javascript code:
[Code]....
And my action method:

company.Id has a value of 10, but company.User.Id is 0. what I'm doing wrong? I've not named any properties incorrectly, by the way.
